Right Lower Lobe

The right lower lobe bronchus is one of the three lobes that composes the right lung. It has "superior", "medial basal", "anterior basal", "lateral basal", and a "posterior basal" segments. The lobes of the right lung are nourished by branches of arteries and veins which stem from the thoracic branch, and these, in turn, stem from the descending aorta.
